ESCRIPTION
The CX02067 is a highly integrated, programmable laser
driver intended for Datacom applications up to 2.1 Gbps.
Using differential PECL data inputs, the CX02067
supplies the bias and modulation current for driving an
edge-emitting laser. The modulation output can be DC-
coupled to the laser diode, giving a significant power
saving over AC-coupled operation.
The CX02067 includes automatic power control to
maintain a constant average laser output power over
temperature and life. In addition, the modulation current
is temperature compensated to minimize variation in
extinction ratio over temperature.
Output flags indicate laser end of life as well as failure of
the APC circuitry to maintain average output power.

Overview
The CX02067 laser driver consists of a high-speed
modulation driver and a laser bias generator with mean
power control (MPC). It is optimized for high speed, low
power operation at 3.3 V supply. Fig. 2 demonstrates the
functionallity of the CX02067.
Modulator
The modulator output stage is designed to drive up to
85 mA in either AC-coupled or DC-coupled mode.
DC-coupled performance depends on the laser used.
The CX02067 modulation output is optimized for driving a
25
load; the minimum required voltage at OUT+ and
OUT- is 0.6 V. To interface with the laser diode, a
matching resistor (RD) is required for impedance
matching. An RC shunt network is necessary to
compensate for the laser diode parasitic inductance,
thereby improving the optical eye. Typical values are
R
SHUNT
= 51
, C
SHUNT
= 3.3 pF
Any capacitive loading at the cathode of a laser diode will
degrade the optical output performance. An inductor is
used to isolate the BIAS pin from the laser cathode.

Mean Power Control Loop
The CX02067 employs a Mean Power Control (MPC)
loop to maintain a constant optical output power from the
laser across temperature, time and power supply
variations. Laser diodes used for communication
purposes come with integrated photo-diodes to monitor
the output power and provide the feedback for the MPC
loop. The MPC loop (or its integrated safety features)
cannot be used without this feedback.
The MPC loop adjusts the laser bias current so that the
monitor current from the photo-diode is matched to a
reference current set by a single external resistor,
R
MPCSET
. The time constant of the MPC loop is
determined by C
MPC
.

(at 6 dB cut off frequency) vs C
MPC
(for nominal process)
Fig. 5 shows the bias current vs RMPCSET over the full
operating temperature range
There are two safety features integrated into the MPC
loop; an Over-Current Alarm and an MPC loop failure
alarm.
The Over-Current Alarm (OCA) circuit limits the
maximum bias current generated by the CX02067. The
bias current limit is set by an external resistor to ground,
R
OCA
. When this limit is exceeded the OCA pin is
asserted LOW. Fig. 6 shows the maximum bias current
limit vs R
OCA.
The MPC loop FAILure alarm (FAIL) is generated by the
CX02067 when the MPC loop can no longer maintain the
constant current set by R
MPCSET
. When the MPC loop
failure alarm is triggered the FAIL pin is asserted LOW.
Enable Control
The CX02067 incorporates a dual polarity laser enable
function with both enable (ENA) and disable (DIS) inputs.
Under normal operating conditions the ENA will be HIGH
while DIS is LOW. Should ENA go LOW (or DIS go HIGH)
both the bias and modulation currents will be disabled.
Wire OR-ing the OCA and FAIL pins externally and
connecting them to the ENA pin will automatically disable
the bias and modulation currents when a failure occurs.
Current Monitors
The CX02067 features bias and modulation current
monitor outputs. The BIAS
MON
output sinks a current
equal to nominally 1/55 of the laser bias current (I
BIAS
).
The MOD
MON
output sinks a current equal to nominally
1/55 of the laser modulation current (I
MOD
). BIAS
MON
and
MOD
MON
should be connected through a pull-up resistor
to V
CC
. Choose a pull-up resistor value that ensures a
voltage at BIAS
MON
greater than V
CC
- 1.6 V and a
voltage at MOD
MON
greater than V
CC
- 1.0 V. These pins
should be tied to V
CC
if not used.

Slow-Start
For laser safety and reliability, the CX02067 incorporates
a slow-start circuit that provides a delay of approximately
200 ns before enabling the laser diode.
Temperature Compensation
The CX02067 features built in temperature compensation
of the modulation current is set using two external
resistors, TC
SLOPE
and TC
START
see Fig. 7.
Current pulled from TC
SLOPE
adjusts the slope of the
temperature compensation whereas current pulled from
TC

sets the threshold temperature for the
